SPECIFICATION forming part of Letters PatentNo. 540,809, dated June 11,1895. A plication as October 19, 1894. semi No. 526,416. on, model.)

Be it known that we, ERICK A. BYE and Osway, residing at Fitchburg, inthe county of Worcester and State of Massachusetts, have invented a newand useful Improvement in Dividers, of which the following is aspecification, reference being had to the accom panying drawings,forming a part of the same, and in which Figure 1 represents inperspective view a pair of dividers embodying our invention. Fig. 2 is atop view of the same with the legs of the divider open. Fig. 3 is acentral sectional view through the clamping-plates and transversely tothe legs of the divider. Fig. 4 represents the recessed surface of oneof the clamping-plates, and Fig. 5 shows a perspective view of theannular washer interposed between the plates.

Similar letters refer to similar parts in the different figures. 4

Our invention rel-ates to that class of dividers which consists of oneor more blocks, or plates, forming the body of the divider in which thelegs of the divider are adjustably held and it has for its objecttorender the instrument more efficient in use and cheaper inconstruction. 7

Referring to the accompanying drawings A, A denote two rectangularplates placed one above the other and held together by a bindingthumb-screw B, which passes through a plain hole in the plate A andenters a screw threaded hole in the plate A. The inner or opposing facesA A of the plates A, A are provided with circular recesses A, asrepresented in Figs. 3 and 4, to receive an annular washer 0 whosethickness-is slightly greater than the combined depths of the recesses Ain the two plates A, A so that when the annular washer C is interposedbetween the plates A, A the two plates-A, A will be held slightly apartas represented in sectional view in Fig. 3, thereby removing allfriction between the v opposing surfaces of the plates A, A and causingthe plates to turn easily upon the washer O as they are rotated aboutthe binding screw 13. CAR MOSSBERG, citizens of Sweden and Nor- Each ofthe plates A, A is provided with a hole D extending through the plateand parallel with its side to receive the legs F, F. The holesD arepreferably placed at equal distances from and upon opposite sides of theaxis of the binding screw'B and they communicate with the recesses A sothe sides of the annular washer C will rest upon and'be pressed againstthe legs F, F as the two plates A, A

are drawn together by the binding screw B.

The binding screw B is provided with a shoulder B between which, and theouter surface of the plate A, is an elastic washer G in order to producea yielding pressure between the plates A, A whenever the binding screwis tightened. A slight loosening of the thumbscrew B serves to releasethe plates so they will turn freely upon the washer O in order to varythe angle of the legs without loosening the legs within the platessufficiently to allow them to move longitudinally.

The two plates A and A are exact duplicates of each other and the entiredevice forms an extremely convenient and eflicient tool which can beused as a divider or as an outside or inside caliper by a substitutionof legs suitable for that purpose in the place of those represented inthe accompanying drawings and the entire device is cheaply constructed.

What we claim as our invention, and desire to secure by Letters Patent,is-- In a divider, the combination of a pair of plates A and A providedupon their opposing faces with circular recesses A annular washer 0 heldin said recesses by which said plates are slightly separated, legs heldin said plates and in contact with said washer and a binding screw B bywhich said plates and washer are clamped together, substantially asdescribed.
